When is cleaning the sidewalks a crime? When you're doing it to create art. Obviously. A number of <a href="http://inhabitat.com/strooks-reverse-moss-graffiti-mural-emerges-from-a-wall-of-the-stuk-arts-centre-in-belgium/">street artists around the world</a> have taken to expressing themselves through an innovative practice known as <a href="http://bldgblog.blogspot.com/2006/11/automotive-ossuary.html" target="new">Reverse Graffiti</a>. Taking a cue from the "Wash Me" messages scrawled <a href="http://inhabitat.com/ben-long-etches-beautiful-reverse-graffiti-drawings-in-exhaust-grime-on-commercial-trucks/">on the back of delivery trucks</a>, they seek out soot covered surfaces and inscribe them with <a href="http://inhabitat.com/reverse-graffiti-hits-munich-streets-and-pays-homage-to-green-vehicles/">images, tags, and even advertising slogans</a> using scrub brushes, scrapers and pressure hoses.
